Obtaining of polystyrene with reduced flammability

A brief description of the process

The method to produce the polystyrene composition with reduced flammability comprises polystyrene modification by creation of a premix with a flame retardant and possibly an auxiliary substance, in order to better homogenize the constituents. As flame retardants are used organophosphorus compounds. In the industrial practice it is favorable to incorporate the process to perform the flame retarding modification into the polystyrene production node.

Advantages of the technology offered

The technology offered reduces flammability of polystyrene in a pro-ecological way, without using noxious, halogen flame retardants.

Equipment

The process can be performed using industrially available apparatus to produce polystyrene.

Advancement of proceedings

Laboratory works have been completed.

Patentability

Patent PL 206936(2010) „Polystyrene composition with reduced flammability and the method to produce the polystyrene composition with reduced flammability”.

Market competitiveness

The solution is competitive in relation to methods to reduce polystyrene flammability with halogen additives, whose application is being restricted by the European Union legislation.
